Title: Improvements in or relating to knitting needles and transfer bits for knitting machines
IPC: D04B9/06
Filed: 1951-01-17
Abstract: 681,136. Knitting. HEMPHILL CO. Jan. 17, 1951. [April 14, 1950] No. 1341/51. Class 74 (ii). A knitting instrumentality and a separate transfer bit are adapted to reciprocate within the same slot and means is provided for coupling (e.g., interlocking) them so that the bit is reciprocable by the instrumentality, the bit being wholly confined within the same space laterally as occupied by the instrumentality when both are wholly withdrawn into the slot and one end of the bit being resilient and so shaped that, when instrumentality and bit are projected from the slot, that end of the bit springs away from the instrumentality, to separate laterally therefrom. A transfer bit is inserted in the same slot as, and under, a dial knitting needle, a butt 8 on the bit entering cut-out 5 on the needle so that needle and bit reciprocate together. The tail 9 of the bit is accommodated under the needle tail 6, of which the lower edge is, for this purpose, at the level of the upper edge of a recess 4 which houses the blade 7 of the bit during rib knitting. This blade 7 is resilient and normally offset and when the needle is projected beyond the normal knitting limit to the transfer position, Fig. 2, the blade springs away from the needle stem and opens the loop for penetration by the associated cylinder needle.

Abstract: 191,617. Harris, H. C. Jan. 16, 1922. Laminar springs.-In devices for connecting together two relatively movable elements of a spring suspension for vehicles, such as a spring and another spring or a frame member, and of the type in which one element has laterally projecting supporting means with conical bearing members thereon to receive upon or within them other conical bearing members carried by the. other element, the conical bearing members are adapted to be positively adjusted for taking up wear by relative moment axially of the supporting means. As shown in Fig. 1, bushings 15 are fixed in an eye in the end of a side. bar 10 of an automobile frame and in the end 12 of a laminated spring 11 and project at 17 beyond those parts to have secured to them ring sections 18 of a roller, or ball, bearing, the sections 18 being coned internally to receive within them rollers 21 and corresponding rings 19 on bosses 20 on the inner sides of side members 13, which are held together in parallel adjusted relationship by bolts 14 passing freely through the bushings 15 and provided with nuts 16. The arrangement allows of adjustment longitudinally of the bolts to take up wear. Preferably, each bearing section is provided with an annular packing 22 which retains grease in, and excludes sand and water from, the bearing. As shown in Fig. 4, tubular shanks 27 of roller bearing cups 28 are secured in the eve of the spring 26, and the co-operating bearing cones 32 are carried bv the inner ends 31 of adjustable studs 29 screwed into the opposite sides of the usual horn 25 at the front of the vehicle and locked by nuts 30. Dust-excluding caps 34 with annular felt washers 35 are arranged over the bearings. In a modified form, bolts are arranged in spring eyes and carry bearing cones at their outer ends, the side members being formed with the co-operating cups and being adjusted and held together by a separate bolt. Instead of antifriction bearings, plain conical bearings 36, Fig. 5, provided with grooves 39 for lubricant may be employed, the cups in this form being provided in the side members 38 and felt washers 40 being provided to exclude dust &c.

Abstract: 830,961. Gravity-separation apparatus. GROOM, R. W. April 17, 1956 [Jan. 17, 1955], No. 1388/55. Class 46. [Also in Group XXIII] Relates to a gravity-separation apparatus for separating naphthalene together with a solvent oil from aqueous detergent liquid and bottom sediments, all of which are removed from a tank being cleaned (see Group XXIII). As shown naphthalene deposits in the tank 7 are dissolved by oil from a tank 4. The solution together with aqueous detergent liquid from a line 10 is removed by suction through a line 9 into a layering container 2 of a separator 1. In the container 2 the mixture stratifies into bottom sediments, which are withdrawn ; detergent liquid, which is withdrawn into a container 3 of the separator, for further use, and oil containing naphthalene which is withdrawn from the top of the container 2. The naphthalene is crystallised out in a tank 11, whilst the oil is recycled -for-further use. Specifications 696,631, 742,844, 808,901, 808,902 and 830.962 are referred to.

Inventor: STAHMANN MARK ARNOLD
IPC: C07D311/48
Filed: 1943-01-27
Abstract: Di-esters of 3 : 31-methylenebis-(4-hydroxycoumarin) are prepared by treating 3 : 31-methylenebis-(4-hydroxycoumarin) with an acyl halide or an organic acid anhydride higher than acetyl halides or acetic anhydride.  The acid halide or acid anhydride is used in excess.  In examples, 3 : 31-methylenebis-(4-hydroxycoumarin) is treated with (1) propionic anhydride.  (2) Butyryl chloride.  (3) Isobutyryl chloride. (4) n-Valeryl chloride.  (5) Isovaleryl chloride.  (6) n-Caproyl chloride.  (7) n-Heptanoyl chloride.  (8) Benzoyl chloride.  (9) Trimethylacetyl chloride.  The reaction may be carried out in the presence of a basic organic solvent.  This must be done if an acyl halide is used, but need not be done if an organic acid anhydride is employed.

Title: Improvements in or relating to valves for steam conduits and the like
IPC: F16K17/32
Filed: 1930-01-15
Abstract: 337,686. Elektrowerke Akt.-Ges., and Krõmer, B. Jan. 15, 1930. Valves actuated by vessels receiving and discharging liquids.-Relates to a rotary plug valve for steam conduits of the kind supported by coaxial trunnions 13 in ball or roller bearings 14, and having slightly-spaced closure surfaces so as to obtain a rapid, though incomplete, closing of the conduit, the casing and plug passages 10, 15 forming together a Venturi passage. In this valve arrangement the pressure difference at two points 31, 35 of the Venturi passage is utilized for closing the valve rapidly in case of pipe fracture. For this purpose the point 31 at the large cross-section is connected by a pipe 30 to a vessel 27 containing mercury &c., and the point 35 at the throat of the passage, is connected to a vessel 28 suspended on a lever 29 and counterweighted at 39. In the event of excess fluid flow, caused, for example, by pipe fracture, the consequent reduction of pressure in the vessel 28 allows mercury to pass from vessel 27 to vessel 28, which consequently falls. This action, through the lever 29 and cord 41, withdraws a catch bolt 23 and releases a weighted arm 25 secured to the spindle of the valve, which is thereupon closed, the closed position being located by a stop 26 on the valve casing.

The heaters 15, 18 are connected in series with resistances 19, 20, 21 which, together with resistances 22, 24, provide biasing potentials for valves 13, 16 and the operating potential for cell 10. The valves 13, 16 are normally biased to cut off. On illumination of the cell 10 current through 22 raises the potential of grid 12 to cause valve 13 to conduct, the current through 24 then raising the potential of grid 25 to cause valve 16 to conduct and operate to the device 29. An arrangement having a. triode output valve is also described, and the output valve may also be a pentode.

Abstract: 1,032,523. Pistons. BRITISH INTERNAL COMBUSTION ENGINE RESEARCH INSTITUTE Ltd. Jan. 6, 1965 [Jan. 15, 1964], No. 1746/64. Heading F2T. The I.C. engine piston of the parent Specification, in which the cylinder clearance volume is variable, is modified by supplying the pressure fluid by way of a non-return valve 6 to a chamber 7 associated with the crown by a pump 4. The pump plunger 4 is operated by a cam surface 2 formed on the small end of a connecting rod 3. A non-return inlet valve 8 allows supply of oil to the pump from a passage 9 in the connecting rod and a spring-loaded discharge valve 11 allows oil to escape from the chamber 7 to the enging sump when the cylinder pressure exceeds a predetermined maximum. In Fig. 3 (not shown), the pump 13 is arranged on the piston of a crosshead engine and operated upon its plunger striking a stationary stop 19. The pump may also be arranged on the moving part of the crosshead. In a modification, Fig. 7 (not shown), the crown is made in two parts, the chamber 7 being formed between a movable piston part 21 and a cylinder part 22.
